Energy Storage Needs for Clean Power Systems and the Potential Support from Electrical Vehicles : A Simplified Assessment on Romanian Case

The last period shown a technology shift trend in both power systems and electrical vehicles, by the increasing use of electrical storage technology. The recent success in both domains shows clearly that energy storage is a significant game changer and that new horizons need to be scrutinized. The paper makes a preliminary assessment on the long-term impact of storage for power systems and for electrical vehicles, in conditions of targeting a 100% CO
₂
free energy production, by making an estimation of storage capacity needed for both domains: power system and electrical vehicles, applied as a simplified assessment on the Romanian case. For estimating the storage needs, the paper presents simulations of renewable energy production based on existing patterns in the Romanian Power System, upscaled to fit a 100% CO
₂
free energy production on selected weekly intervals compared with weekbased consumption profiles. The paper shows that strong or full penetration of electrical vehicles has the potential to be main driver in helping power systems to mitigate stochastic renewable production with the necessary storage means, to pursue 100% clean energy goals. Moreover, the two domains have synergies and reciprocally help each-other in reaching a global goal of clean energy and transportation.
